CAR-AXLE JOURNAL-BOX.

Specification of Letters Patent.

Patented May 1, 1906.

Application filed July 27, 1905. Serial No. 271,481.v

lState of Montana, have invented certain new and useful Improvements in Car-Axle Journal-Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a art hereof.

y invention has relation to improvements in car-axle journal-boxes; and it consists in the novel construction and arran ement of details more fully set forth in t e specification and pointed out in the claims.

In the drawings, Figure l is a side elevation of the journal-box and car-axle assembled. Fig. 2 is a middle vertical longitudi- 1 nal section of the same, the axle-sections being in elevation. Fig. 3 is a transverse vertical section on line 3 3 of Fig. 2. Fig. 4 is a transverse vertical section on line 4 4 of Fig. 2. Fi 5 is a transverse vertical section on line 5 5 of ig. 2. Fig. 6 is a top plan of the journalboxwith cover-plate partly removed. Fig. 7 is an end view of the journal-box. Fig. 8 is a perspective of the grooved bearing-block for the middle of the axle. Fig. 9 is a transverse vertical section on line 9 9 of Fig. 6, and Fig. 10 is a transverse vertical section on line 10 10 of Fig. 6.

The object of my invention is to'construct a journal-box for car-axles (and specially for sectional axles) which will be thoroughly dustroof; one providing ready means for the oiling of the axle; one making the necessary provision for the removal of all wearing parts by the replacin of worn bearinglocks; one which may e readily assembled or taken apart; one which is cheap, durable, and easily manufactured; one requiring a minimum amount of machine-work; one using stock material for the axles; one requiring a minimum weight of metal; one insuring against the se aration of the axle-sections; one which wil positively prevent the waste of the lubricant; one furnishing easy means for conducting the lubricant to surfaces where desired; one retaining the axes of rotation of the sections of the axlein ermanent alineinent, and one possessing rther and other advantages better apparent from a detailed lescription of the invention, which is as folows:

Referring to the drawings, W represents the car-wheels, and 1 1 the sections, of the, axle attached thereto, as usual. Inclosing the axles is the shell or journal-box 2, the bottorn of which is preferably V-shaped in crosssection to allow the oil to drain to its proper receptacles, as subsequently to appear. The

top of the journal-box at opposite ends thereof is extended into the form of lateral wings 3 3, which are provided with bolt-holes 4 4, by means of which the journal-box may be attached to the car-truck. The opening between the wings 3 is closed by a cover-plate 5, said opening being left to simplify the casting and construction of the journal-box and to furnish access to the interior of the box when assembling and replacing the parts confined therein. The cover-plate 5 rests with its opposite edges on the longitudinal outwardly-projectinv flanges 6 6, formed with the side walls of the box, said flanges furnishing a means of attaching the cover-plate to the journal-box by bolts or cap-screws 7, the ends of the plate being supported on the flanges 6', formed on the inner edgesof the wings 3 and disposed in the plane of the flanges 6. The cover-plate 5 when in position is flush with the wings 3, the flanges 6 6 being depressed sufficientl below the upper surface of the wings to allbw for the thickness of said cover-plate. The o posite ends of the journal-box-2 are provi ed with the annular or circular flanges 8, which fit corresponding grooves in the wheel-hubs, the connection thus resulting being absolutely dustroof, so that no dust can find access into the interior of the journal-box when the parts are once assembled.

Confined within suitable pockets or depressions formed in the center portions of the wings 3 behind the flanges 6 are replaceable bearing-blocks 9, which serve to su port the weight of the truck and car upon t e axles and which furnish a bearing-surface gainst which the axles may revolve. The blocks 9 occupy the space between the flanges IOO 6 and the terminal walls of the journal-boximmediately beneath the win s 3 and embrace the axle along the upper alf of its pef ripheral surface, the inner faces of the blocks serving as abutments for the adjacent ends of the retaining-rings 10, which in assembling the device are slipped over the axles 1l and are attached thereto by means of screws IOS s, sus MACHINE ELFMFMTS;

or cap-bolts 11. v The rings 10, bearing as they do against the adjacent faces of the bearing-blocks 9, prevent the axle-sections from separating and loosening from their places, as is obvious.

Supporting the inner ends of the axle-sections is an intermediate bearing-block 9', embracing the axle along the lower half of its peripheral surface, the block being supported on pairs of seats 12 12, separated by a longitudinal space 13 to allow for the passage of oil at the bottom of the journal-box 2, and by a transverse space 14 to accommodate a lubricating chain or wick (not shown) used for the purpose of carrying up the oil 4from the bottom to the bearing-surfaces. The ends of the bearing-block 9 are provided with central grooves or recesses 15 to furnish a port or opening by which the oil lying at the bottom of the space or oil-receptacle 14 may be brought up to and applied at the top of the axles for lubricating them either by means of an endless link chain or by a wick which shall draw the oil to suitable felt or lcottonwaste packing filled into the box or compartment 16, formed above the axles between the walls or central diaphragms 17. The diaphragms 17 are cast with the j ournal-box and serve as means both for guiding the bearingblock 9 into position on its seats 12 12 and reventing displacement thereof when once owered into position, the said diaphragms being suitably bored to accommodate the ends of the axles 1 and prevent them from being thrown upward from their seats upon the bearing-block.

Formed with the inner walls of the journalbox 2 and disposed substantially in the transverse planes touching the inner edges of the wings 3 are the diaphragms 18, which divide the bottom of the journal-box into contiguous oil receptacles or basins 19 20, respectively, between which communication is established by a port or passage-way 21, which allows the oil to run from the one basin 19 into its contiguous basin 20. The space above each basin 19 is filled with felt or cotton-waste packing which conducts the oil to the wearing-surfaces between the parts 1, 9, and 10. The oil is introduced through a hole 22, bored from without inward, the oil illing the intermediate reservoir 20. The hole may be bored through the center of the axle diagonally, as shown, and closed by a plug 23.

The basal inclined or V-shaped walls of the journal-box form a basin extending the full length of the journal-box for the collection of the lubricating-oil, the diaphragms 17 and 18 forming, respectively, the central compartment 16 and terminal compartments 19 19 for insertion of cotton-waste, felt, or equivalent oil-carrier and forming in addition the intermediate oil-receptacles 20 20, which serve as storage-receptacles for the oil subsequently fed to the waste in the contiguous compartments 16 and 19 The position of the receptacles 20 is such that the oil stored therein cannot overflow or become wasted, being only drawn upon in proportion as the same is needed for oiling the surfaces between the several bearing-blocks and the axle. By removing the cover-plate the interior of the journal-box is made readily accessible and any of the worn parts are easily, removed and replaced' by new parts.

Having described my invention, what I claim is- 1. In combination with an axle, a journalbox having means for attachment to the cartruck, upper terminal bearing-blocks for the axle located within and adjacent to the ends of the journal-box, a central lower bearingblock for the axle, the body of the last-mentioned block being provided with grooves for the free passage therethrough of the lubricant, supporting-seats for the block, and a bottom basin extending the length of the journal-box for supplying the lubricant, substantially as set forth.

2. In combination with an axle, a journalbox having means for attachment to the cartruck, upper terminal bearing-blocks and a lower intermediate bearing-block for the axle, suitable compartments formed in the journalbox for the housing of the bearing-blocks, and supply-reservoirs communicating with the several compartments for conducting oil thereto, substantially as set forth.

3. In combination with an axle, a ournalbox having bottom inclined walls forming a common basin extending the full length of the journal-box, and a series of transverse diaphragms forming contiguous compartments in communication with said basin, substantially as set forth.

4. In combination with an axle, a journalbox having means for attachment to a cartruck, terminal compartments for the-housing of suitable bearing-blocks, a central compartment for receiving a bearing-block, supporting-seats at the base of the compartment for said central bearing-block, said'scats being spaced both longitudinally and in a lateral direction, and oil-receptacles formed in the bottom of the journal-box on each side of the central compartment and contiguous to the terminal compartments and in communication with the several compartments, substantially as set forth.

5. A journal-box for car-axles com rising a box open on top, a cover-plate there or, terminal wings exterior to the cover-platefor attachment to a car-truck,diaphragms formed with the journal-box at each end forming terminal compartments and intermediate cornpartments contiguous thereto, passage-ways beingformed in the diaphragms for establishing communication between the compartments, central diaphragms spaced a suitable distance to form a middle compartment, suit- IIO la; n

blocks in seid terminal compartments, and reservoirs for supplyin oil to the several compartments, substantie ly as set forth.

In testimony whereof I a'ix my signature in presence of two Witnesses.
